Route Request Mediation Apparatus for Dynamic Bandwidth Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In networks with central control, existing configurations require an intermediate server for bandwidth allocation, leading to inefficiencies when policy servers cannot secure necessary line bandwidth, resulting in overreservation and decreased utilization.
Innovation Solution
A route request mediation apparatus that manages network resources, receives requests with service level conditions, forwards requests to destinations, and assesses acceptance based on negotiation status and resource availability, allowing for resource allocation without an intermediate server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bandwidth allocation intermediate server is introduced to manage bandwidth allocation across multiple ISPs, then bandwidth allocation capability is improved, but device complexity increases and the system requires additional intermediate servers to coordinate between central control apparatuses
Solution Approach 1:
The patent introduces a bandwidth allocation intermediate server that acts as a mediator between policy servers of different ISPs. This server receives bandwidth allocation requests, coordinates with relevant policy servers, and manages the allocation process centrally, enabling multi-ISIP bandwidth allocation without requiring direct complex interactions between multiple control apparatuses.
Solution Approach 2:
The bandwidth allocation intermediate server autonomously manages the bandwidth allocation process by automatically communicating with policy servers, assessing available bandwidth, and making allocation decisions without requiring manual intervention or complex coordination protocols between multiple control systems.
2Reliability
If policy servers reserve line bandwidth in advance to guarantee service levels, then service reliability is improved, but line utilization efficiency deteriorates when reservations are excessive or delayed releases occur
Solution Approach 1:
The bandwidth allocation intermediate server implements a feedback mechanism that continuously monitors actual bandwidth usage and reservation status. When it detects that reserved bandwidth is not being utilized or that service levels are already met, it automatically sends release commands to policy servers to free up excess reserved bandwidth, thereby improving line utilization while maintaining service guarantees.
Solution Approach 2:
The system transitions from static bandwidth reservations to dynamic bandwidth management. The bandwidth allocation intermediate server continuously adjusts bandwidth allocations based on real-time network conditions, user实际需求, and service level requirements, allowing bandwidth to be reserved when needed and released when not required, thus optimizing both reliability and utilization efficiency.
3Loss of information
If the bandwidth allocation intermediate server transmits detailed policy information between communication apparatuses, then allocation transparency is improved, but information transmission complexity and processing overhead increase
Solution Approach 1:
The bandwidth allocation intermediate server serves as an information intermediary that centralizes the collection, processing, and management of bandwidth allocation information. Instead of having multiple policy servers exchange detailed policy information directly, all allocation requests and status information flow through this intermediate server, which simplifies information management and reduces processing complexity while maintaining full information transparency.

AI summary
A route request mediation apparatus comprises a resource management unit that manages a resource of a network to be managed; a request receiving unit that receives a route request with an added service level condition from a user or another route request mediation apparatus; a negotiation status management unit that forwards the route request to a destination specified by the route request, and manages a negotiation status based on a response from the destination; an acceptance assessment unit that assesses whether or not to accept the route request by referring to the negotiation status managed by the negotiation status management unit and to the resource management unit; and a response sending unit that responds with an assessment result that indicates whether or not the route request is accepted to the request source of the route request.
